Specifications for the installation
The tightening torques specified in the table "Tightening torques for screw connections" must
be observed.
Carefully insert the plug connections and ensure that they are secure.
When using connectors with a locking mechanism, make sure that the locking lever is
securely engaged once connected.
The fiber optic cable plugs must be remounted at their original slot. Fiber optic cables and
sockets are accordingly labeled for correct assignment (U11, U21, U31).
The DRIVE-CLiQ cable connectors should be labeled prior to disassembly and reinstalled at
their original slot, since it is necessary to re-perform system identification after changing the
DRIVE-CLiQ cables.
The screw connections for the protective covers may only be tightened by hand.
